Data center processed often uses water cooler 1 to start, and flow out cooling water for the water outlet of evaporator 1a, and a part supply data center supplies water
End 7 meets the cooling needs of data center, and another part flows into cold-storage water pot 3 and is stored therein cooling capacity, from cold-storage water pot 3
The recirculation water of water and data center's backwater end 7 after the heating of outflow is back in evaporator 1a again to be dropped again
Temperature so recycles；
(3) cooling tower is data center's cooling supply, is cold-storage water pot cold-storage: opening valve V3, valve V4, valve V5, valve
V6, valve V7, valve V8 close valve 1, valve V2, valve V11, valve V12, and PLC controller controls cooling tower starting, cold
But the cooling water of tower outflow flows through being dropped again for being back in cooling tower after cold side absorption heat heating for plate heat exchanger 4
Temperature, and meet data center for water end (W.E.) 7 from the cooling water a part supply data center that cold side flows out that changes of plate heat exchanger 4
Cooling needs, another part flow into cold-storage water pot 3 simultaneously cooling capacity is stored therein, from cold-storage water pot 3 flow out heating after
The cold side of changing that water and the recirculation water of data center's backwater end 7 are back to plate heat exchanger 4 again cools down again, so
Circulation；
(4) data center often uses water cooler 1 and cooling tower while being data center's cooling supply, 3 cold-storage of cold-storage water pot: opening
Valve 1, valve V2, valve V3, valve V4, valve V5, valve V6, valve V7, valve V8 close valve V11, valve V12,

Meet the cooling needs of data center for water end (W.E.) 7 to data center, another part flows into cold-storage water pot 3 and cooling capacity is stored in it
In, it is back to evaporator 1a again from the recirculation water of water and data center's backwater end 7 after the heating that cold-storage water pot 3 flows out
In cool down again；The cooling water of cooling tower outflow flows through absorbing after heat heats up for cold side for plate heat exchanger 4 and is back to
Cool down again in cooling tower, and supplies data center from cooling water a part that cold side flows out of changing of plate heat exchanger 4
Meet the cooling needs of data center for water end (W.E.) 7, another part flows into cold-storage water pot 3 and is stored therein cooling capacity, from cold-storage
It is cold that the recirculation water of water and data center's backwater end 7 after the heating that water pot 3 flows out is back to changing for plate heat exchanger 4 again
Side cools down again, so recycles；
(5) cold-storage water pot 3 is data center's cooling supply as emergency cold source: opening valve V4, valve V6, closing valve V11,
Valve V12, the cooling water supply data center flowed out from cold-storage water pot 3 is for water end (W.E.) 6, the recirculation water of data center's backwater end 7
It flows into cold-storage water pot and cools down again；Under this operating condition, data center is often with water cooler 1 because the reasons such as power loss lead to its nothing
Method starting, then PLC controller switching cold-storage water pot 3 is the timely cooling supply of data center as emergency cold source；
(6) it is data center's cooling supply that conventional cold source water cooler 2, which is used as spare cold source: valve V11, valve V12 are first opened,
Valve V9, valve V10 are turned off, conventional cold source water cooler 2 works, from the cooling water supply data that its evaporator 2a flows out
The heart is for cold end 6, and the recirculation water of data center's backwater end 7 then flows back in evaporator 2a and cools down again, so recycles, with full
Sufficient data center's cooling needs；Under this operating condition, data center often use one or more in water cooler 1 because of originals such as equipment faults
Because when being unable to run, conventional cold source water cooler 2 will be accessed data center in cold loop, as standby automatically by PLC controller
It is come into operation with cold source, it is that data center carries out cooling supply that cold supply system, which will always remain as conventional cold source water cooler 2, at this time, is needed
Operator, which checks in time and solves data center, often uses 1 problem of water cooler, through hand-reset side after trouble shooting
Data center can often be put back into water cooler 1 again, be data center's cooling supply, then PLC controller again will be normal
Rule cold source water cooler 2 is cut out again as conventional load cooling supply.
The beneficial effect of the present embodiment is: (1) being often included in conventional cold source water cooler with water cooler with data center
Under same control system, reduce the cost of system；It (2) can be using conventional cold source water cooler as standby when coping with emergency case
With cold source, the selection diversity of reply is increased, the supportability of cold supply system cooling supply is improved；It (3) is number using cooling tower
